To 11 whom. it 11111 11 concern lle it kuown't'hat I. .loux Lixns.ot' Water- -hury. in the county of New Haven and State of Connecticut.- have invented a new linprovement in Valves: and l do herehy declare the followin when taken in connection with theaccompanying drawings and the letters of reference marked thereon to he a fun, clear. and exactdescription of the same. and which said drawings constitute part of this specification:and represent. in-

My invention relates toan improvement in that class of valves primarily designed to he used in pneumatic tires for bicycles. the ohjectheing to prodm-eQa simple. compact and convenient .val-ve constructed with particular reference to convenience of application to and removal from the tuhular valvecasing; to locating the valve-seat in uniform position therein. and to compressing the seat packing so as to make it peculiarly ettective.

With these ends in view my invention consists in certain details of construction and (UlIlbilltlt'lOlIS of parts as will he hereinafter described and pointed out in, the claims.

In carrying out my invention as herein shown, I employ a valve-seat having its inner end. formed with an :lnnular hevel a, and with a central perforation A for the reception of the. stem B of the valve 13', which is provided at the base of the stem with a packing B, which co-acts with the bevel mot the valve seat. The said valve seat and valve are located within ,an externally threaded tubular 'al\'e-c: ising which may be of any approved construction. and which is adapted to he applied to a pneumatio tire and a wl-leel-rim. "The said casing is formed with an internal annular shoulder 0, 'with which the valve-seat is engaged. and which insures its uniform location in, the casing. the outer portion of the bevel a of the seat resting upon the said hevcled shonlder. By providing for seating the valvc-seat'upon a shoulder within the valve-casingif am enahled to secure a uniform action of the valve. by making the valvwsprings I) nnitorm in length. The valve-seat is held in place by means of an extcriorly threaded tuhular plug. which is entered into the internally threaded outer end oi the casing, the inner end of the said plug impinging against a valve-s'at packing l. which is placed against the outer face of the valve-seat. The said plug is formed with a transverse slot c. which permits it to he turned into place and \vitlnlrawn hy means of a screwdriver. lt is designed to turn the plug inward so as to impose saith-tofu pressure upon the packing F. to cause tic same to he squeezed outwardly against the inner walls of the casing, s as to form a perfectly tight joint. The stem ll of the valve H" is extended outward through the plug. and upset to form a retaining-head 13. which therefore couples the walvc. valvc-seat and plug together so that when .oncc assembled they arethereafter handled as" one piece. with obvious convenience.

It is apparent.thatfunder this construction the valve and valve-scat may he easily withdrawn from the tubular casing by reversely rotating the plug by means of an ordinary screw-driver. I do not limit myself to using my improvement in connection with the particular valvc-structure shown and described in which the tubular alvecasing is provided with a plate-like few der (L a nut (7 which hears upon the wheelrim. and a reniovahle -ap for closing the using which is secured to the tire proper by means of a clamping-plale (E and .a not In the modified construction shown'in Fig. 6, the valve-seat (l is formed with a tubular stem G. which is upset within the inner end of the plug ll. so that the seat and plug are virtually swivclcd together with the valve seat packing l between them. Tnthis con struction the stem J of the valve J passes through the seat (2 and its tuhular stem,

hut is not positively connected therewith. so

that. although the valve seat and the plug are permanently coupled together. the valve and valve-stem are not united to them. In

this construction thevalve-seat is withdrawn from the iasing when the plug is withdrawn, by reversely rotating it. hut the valve and valve-stem are left within the casing, from which, however, they may readily be shaken out as there is nothing to bind or restrain them.

In view of the modification sug ested, and

of others that obviously might e made, I

would have it understood that I do not limit myself to the exact construction herein shownand described, but hold'myself at liberty to make such changes and alterations as fairly fall within the spiritand scope of (her, of a valve-seat bearing'np'on the said v shou'lderewhich locates it--proper ly within the said casing, a plug insertedintothe cas- 20' ing for holding the Rat in place a packing interposed between the valve-seat-and ;plug, and a spring-actuated. valve .co-acting d1- rectly with the'said valve-seat.
